Builder magazine readers gave Calculated Industries the #1 Quality Rating for Builder Instruments in a recent survey. It is the third time the company has earned the top rating. The company makes several products for the construction industry, including the Construction Master line of construction-math calculators and Scale Master digital plan measures.

The 2007 survey sampled more than 10,000 of the magazine's 120,000 subscribers who define themselves as builders, builder-developers or general contractors. Those surveyed are asked which brands they know best, which ones they use the most, and which they rate highest in quality. Other companies mentioned in the survey included DeWalt and Zircon.

Founded in 1978, Calculated Industries is a leading manufacturer of specialty calculators and electronics for business and industry. CI has developed tools for tasks ranging from construction, architecture, real estate and lending to home projects, graphic arts, cooking and quilting. The company, which moved to Carson City in 1994, employs 55 people at its Carson City headquarters.
